Do you have an example, like an image or something to share to give us an idea of what ticker tape is?

Ticker Tape like the one shows on the news of any TV station.

Please check this Ticker tape sample:

The Tape was made using J query.

It is a great tool to show standard information..or stock market information.

Let me know if you need any additonal information and thank you so much for your help.

Alec,

I often do a static ticker on my documents - you can build one simply by concatenating different expressions and legends together. It is a great way to get the headline information for the data visible on each page.

I've not made one of these scroll before, and always kept the amount of data to what would sensibly fit on a single line. If you need a scroll then you probably want to use an extension - in which case you can embed JavaScript etc.

I think a ticker-tape can only be achieved when you embed HTML (and optionally javascript) to a QVW. I think that can be done through an extension (I didn't make extensions so I'm not sure).

The ticker in Qlikview that srikanthsri1 refers to is in my opinion a creative and funny implementation, but on my pc it runs far from smooth...

Thxs Srikanthsri1 for the thread. it is exaclty what i am looking for but .

the text is moving and stoppoing and moving and stopping..

Is it possible to make it move constantly. how to controll the speed of the text.

I looked at the expression: =left(MyText,5*mod(round((now()-now(2))*86400),ceil(len(MyText)/5)+5))

but I didn't understand it..

Anybody can help explaining it.

Thxs,

Alec

I don't know if it is less of an issue in the more recent versions, but referring to now() in a function like that was a surefire way to cause a QlikView 8.5 document to slow to a crawl. All other calculations are put on hold each second as the expression including the now() statement is refreshed.

My understanding is that when implementing the extentions these were made asyncronous, so that Flash and JavaScript could run in an extension object without impacting the rest of the document.
